Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cutting blade on the leading edge of a bottom plate of a machine frame.

Conventionally, in this type of plucking machine, the impeller of the blower and the drive boob 1 for driving the cutting blade were both directly connected to the output shaft of the engine.

Therefore, when trying to adjust the cutting speed of the cutting blade,
Previously, the only option was to operate the engine's throttle (-) or adjust the diameter of the drive pulley. However, with the former, the cutting speed of the cutting blade and the rotation of the impeller also changed significantly. When the engine is decelerated, it greatly affects the ability to collect tea leaves, and the engine's maximum capacity is not effectively used.

Further, according to the latter, a tool is required for adjusting the diameter of the boob, and a large gear ratio cannot be obtained.

The present invention focuses on the phenomenon that when the intake port of the blower or the discharge port of the blower pipe is blocked, the engine speed naturally increases even though the engine's throttle lever or drive pulley diameter is not operated. By providing an opening adjustment device at the suction port or the discharge port and varying the area of the suction port or discharge port, tea leaves can be picked at a pinching speed that is suitable for the condition of the tea plants that are growing in large numbers.

Next, an embodiment in which the present invention is applied to a two-person portable system will be described with reference to the drawings.

(1) is the air pipe that also serves as the bottom plate, (2) (25 is the side plate, (3) is the top plate, and (4) is the partition plate, which together form the machine frame with open front and rear sides. .

(5) (0 is the rotor on which the rotary blades (6) (6') are fixed, one end is mounted on the side plate (2) (2'), and the other end is fixed on the partition plate (4). It is connected to the bevel gear (4) and mutually rotates within the machine frame.

(7) is a fixed blade fixed to the front edge of the bottom of the air pipe (1).

0υ is the casing of the impeller (8), and the air outlet α of the casing communicates with the air pipe (1). 0 is the inlet.

ano (2), fist, is a number of discharge ports drilled at appropriate intervals in the blast pipe (1), and the opening adjustment device α3 adjusts the pitch of each discharge port from α to α with a long hole at one end. The rail 07) 09 on the rear wall of the blower pipe is connected between the shutter plates with αQ and
At the same time, the elongated hole q0 is inserted through a bolt (to) at one end of the rear wall of the blower pipe, and the shutter plate (a) slides left and right within the range of the elongated hole oo to open the discharge port. 0z04...
The area of ・is to be varied and fixed at an appropriate position with butterfly nuts) (1'J).

The transmission pulley Qυ is fixed on the input side, and the reduction gear drives the rotor (5) (55) on the output side.

(A) is a V-belt installed between the drive pulley Ql and the transmission pulley Q■. (E) (Foundation) are the handles on both sides of the machine.

Therefore, when the engine (9) is operated, the impeller (8)
rotates and the pressure air is sent to the outlet Q2 (b) of the blower pipe (1).
... is discharged toward the storage bag at the rear of the machine frame.

On the other hand, the rotation is transmitted from the drive pulley Moe to the transmission pulley Qυ, the reducer, and the rotor (5) (55), and the tea and sweets are transmitted to the rotor (55).
5) (Rotary blade (6) fixed to 55) (It is sandwiched between 65 and fixed blade (7), and the outlet (6) of the blow pipe (1)
2) The leaves are collected in the storage bag by the pressure air discharged from...

Then, to change the rotation speed of rotor (5) (55),
This may be done by changing the diameter of the drive pulley, but
When you don't have the tools and want to change gears in a hurry,
Alternatively, if you want to increase the shifting width, move the shutter plate (G) to the right or left to increase or decrease the opening area of the air outlet (2), (6), etc. of the air pipe (1). good. That is, by increasing or decreasing the discharge port area, the blowing power load to the engine (9) is increased or reduced, so that the rotation of the engine (9) naturally increases or decreases. When the rotation of the engine increases or decreases, the rotation of the rotor (5) (55) similarly becomes high or low.

For example, when picking a relatively heavy tea confectionery with a large number of buds, such as Ichibancha, open the discharge port (2) α so that the maximum amount of air can be discharged, and the engine Since a large amount of the output is consumed as blowing power, the rotation speed is suppressed, and in the end the rotor (5) (55 rotates at a low speed, and there is no double or triple cut due to the high speed rotation of the rotor, so the tea cake is cut into pieces. Leaves of good quality can be collected.

In addition, in the case of mowing work where the cut tea confectionery is discarded between the tea furrows, there is no problem even if the confectionery is cut into pieces, and the condition of the tea furrow after mowing, that is, even the mowing marks, is good. If you have one, it is best to rotate the rotor at high speed and tightly cut the tea leaves.

In the case of taming and cutting, there is no need to collect the tea leaves into a storage bag, so if you close most of the outlet (2) e..., the air volume will be greatly reduced, and the 〜Evening<5)
(Since 55 rotates at high speed, tight cutting is possible.
Furthermore, if the diameter of the drive pulley 00 is also varied at this time, a wider shift range can be obtained, and the picking operation can be performed at the most suitable rotation speed.

The present invention is not limited to the above-mentioned portable type, but may be of the so-called self-propelled type or semi-self-propelled type as long as the blower and the cutting blade are driven by the same prime mover. ,
Even for Sanbancha, etc., it is possible to change the speed of the rotor by changing the mouth to the optimum size according to the properties of the fresh leaves by the same operation. Note that the opening adjustment device αj of the suction port or the discharge port can be adjusted by the above-mentioned method. Not limited to the shutter plate (g) in the example, in short, any type of type that can variably adjust the area of the opening will produce the same effect.
